Working Principles

The LM26420Q1XMH/NOPB DC/DC switching regulator is a linear regulator that works on the principle of feedback control. It uses a voltage reference and error amplifier on the input side, and an output Stage controller and PWM switching device on the output side. The voltage reference and error amplifier monitor the output voltage and provide an input to the output stage controller based on the desired value and the current input voltage. The output stage controller then performs a pulse width modulation (PWM) to control the switching of the output device in order to regulate the output voltage to the desired value. This works in both regulating and current-limiting modes.

The LM26420Q1XMH/NOPB features an adjustable range of 1.2V to 14V, with no external power source required. It also features an adjustable switching frequency up to 2MHz, allowing for greatly increased efficiency, compact designs and reduced external components.

Advantages of the LM26420Q1XMH/NOPB

The LM26420Q1XMH/NOPB is designed with a long life availability in mind, providing reliable long-term power supply without concerns of degradation. It offers high efficiency, with up to 94% efficiency in PWM mode and up to 97% efficiency in pulse frequency modulation (PFM) mode. The LM26420Q1XMH/NOPB DC/DC switching regulator also provides a wide range of output voltages, and a wide variety of current requirements, making it suitable for a wide range of applications.

In addition, the LM26420Q1XMH/NOPB is equipped with several protection features, such as over-current protection, thermal shutdown and foldback current limit. These features, combined with the long-life package, make the LM26420Q1XMH/NOPB a reliable and trustworthy power supply for any embedded system.

Conclusion

In conclusion, the LM26420Q1XMH/NOPB is a suitable DC/DC switching regulator for a wide range of applications, due to its high efficiency, long life availability and adjustable range of output voltages and currents. Its small size and easy programming makes it an ideal choice for applications such as motor drives, portable electronic devices, robotics, and any other application where a reliable and high-efficiency power supply is required.
